"""Tests for the light-mode terminal detection + color remap in cli.py.
Covers the env-override path and the SkinConfig.get_color() wrapper that
the resize / light-mode salvage installs at module import time. We don't
try to fake an OSC 11 reply — the env-override branch short-circuits
before the terminal query, which is the path most users hit.
